Abstract

Epitaxial magnetic oxide films can be reversibly strained on piezoelectric monocrystalline substrates of Pb(Mg_1/3Nb_2/3)_0.72Ti_0.28O₃(PMN-PT). The magnetic film/piezoelectric substrate sample that undergoes well-defined biaxial, nearly linear strains exceeding 0.1% provides a model system for the inspection of strain-dependent magnetic properties which are exploited in many two-phase magnetoelectric multiferroics. We review the properties of the applied pseudocubic PMN-PT(001) substrates, and summarize results for the strain-dependent magnetization of ferromagnetic manganites (La, A)MnO₃ (A = Sr or Ca).
